From publisher blurb: The Specializations Setting Rule in Savage Worlds tends to get a bad rap, but if it's applied properly and carefully, I think you can get a lot of mileage out of the rule. How To: Skill Specialization aims to place a spotlight on when to use the rule, the best ways to implement it, and how it interacts with Edges such as Jack-of-All-Trades or rules such as Familiarization. This requires a copy of Savage Worlds Adventure Edition to use.
